Sensitivity Analysis Using Simulation Worksheets in BlockSim and DOE++

The combination of simulation methods and reliability block diagrams (RBDs) in reliability and maintenance analysis provides a powerful tool for estimating different system performance metrics (such as availability, maintenance costs, throughput, etc.) and identifying areas of improvement. A great benefit of this methodology is that it can then be used to perform sensitivity analysis in order to investigate the effect of different design options or maintenance policies on system performance. This article will illustrate how simulation worksheets in BlockSim can be used for this purpose.
